bile use, he sold and delivered to the customers in original, sealed packages, so that themotorist will not be cheated by the substitution of inferior oils. Up to the present time the only package which has been successfully used is the tin can which is purchased on the spot and drained into the engine casing. This has a number of objections, however, first due to the exgo pense, but more especially due to the difliculties of disposing of the old cans. This has become a very grave problem to the oil companies, and

it is the object of the present invention to construct a container which, after use, can be readily as destroyed by burning. The container is oiland grease proof, and will not leak. It is in general conical form, although this exact shape is not essential. The end can be cut off and the tip placed in the spout so that the container becomes its own funnel. The containers are inexpensive and efilcient. They can be easily packaged and distributed, and when used can be burned. The containers when empty can be nested for shipment.

The, invention also comprises the method for making the new container, it being understood that both the article and the method of making are subject to modification within the scope of the invention as set forth in the claims.

In the drawings in which the best known or preferred form of the invention is disclosed:

Fig, 8.1:. an enlarged detail of the lower end' showing a further deshowing the manner in which the oil proof peak, or apex, is secured.

The body, or main portion, of the container is made from a suitable paper stock, or the like, which preferably is combustible so that the emp- 5 tied container may be burned, and is in the form of a substantially semi-circular blank. This may be cardboard, straw-board, or a like material, and is indicated at i. It is preferably brought to a feather edge along the straight edge of the 10 blank,"'either by stepping ofi successive, laminations as shown at la, b, c, or by using a sheet tapered in thickness. Over the upper surface of the base is adhesively secured an oil and grease proof sheet 2. For this sheet any of the usual 15 materials for this purpose may be employed. For this purpose, sheets of regenerated cellulose sheeting have been used, but any other similar sheeting, which is oil proof, is possible. The sheet should be flexible and capable of adhering to the base l. 20 The composite sheet is provided preferably in semi-circular.-blanks, such as shown in Fig. 1, the top or inner side of the base being covered with the sheet 2, which extends below the straight side of the blank to form adepending, flexible 25 skirt 3. The container is then rolled up in the form of a cone about the point t, which is located at the center of the edge of the body. For this purpose, the blank may be rolled about a cone, or form, this purpose.

It is noted that the point a which'forms the apex of the cone is above the skirt portion 3, so that, as the cone is rolled up, the skirt will be folded over to form a pocket 5, as shown in Fig. 8, and as the rolling continues this pocket -will be formed and rolled up at the apex to afford a tight, leak-proof seal. A plug of glue, or other plastic material, may be used in the tip to assist in the sealing. Such a plug is shown 40 in'dotted lines at 9 in Fig. 5.

In order to adhere the several, convolutions together, the upper surface of the blank is covered with an adhesive over its entire area, except that portion which forms the inside surface of the container, the adhesive also extending over the skirt. ,This area isshaded in Fig. 1 and is indicated by the numeral 6. Instead of applying the adhesive to the top of the blank it may be applied on the under side, in which case the position of the adhesive area will be reversed from that shown, so as to keep adhesive from the outer surface of the container. A strip or block of adhesive is also applied to the upper surface of the pocket fold as shown at I in Fig. 8, if the first pro- 55 upon any of the standard machines for 30 ably made of several laminations of the board The stock used for the layer 2 does not retain the oil as does the metal container, and it is possible, therefore, to save excess oil which it is required be placed in the tin containers to compensate for the oil remaining in the tins. The cheapness and ease of destruction of the containers are major advantages which, with others, makes a valuable form of container. While the conical form is preferred, other forms may be used, and the invention is not restricted to exact conformity to the details as shown. For example, the container may be pyramidal, or any other form which may be suggested. If desired, a cap may be placed over the tip of thecontainer to protect it from accidental injury.

What is claimed is:

1. A readily destructible container for oil or the like, comprising a body tapering at one end and having a closure at the other end, said body consisting. of convolutions of a comparatively heavy paper stock, an inner lining repellent to oil, and a pocket constituting a seal at the apex formed from an integral extension of the lining folded upon itself and enclosed in the convolutions.

2. A readily destructible container for oil or the like, comprising a body tapering at one end and having a closure at the other end, said body consisting of convolutions of a comparatively heavy paper stock, an inner lining of a regenerated cellulose sheeting repellent to oil, and a pocket constituting a sea] at the apex formed from an integral extension of the lining folded upon itself and enclosed in the convolutions.

3. The process of making containers, comprising forming a semi-circular blank of a paper stock covered with an oil proof lining, the lining extending beyond the straight edge of the paper stock, and forming the stock into a cone, the apex of which is located within the edge of the lining, and folding the projecting edge of the lining into a pocket which constitutes an oil seal at the apex of the container.

4. The process of making containers, comprising forming a blank of a paper stock covered with an inner 011 proof lining, the lining extending beyond the straight edge of the stock, rolling the stock and the lining into a cone, the apex of which lies inside the edge of the lining, and folding the projecting lining edge into a pocket at the apex of the container during the rolling operation.
